Application filed October 26, 1915; Serial No. 58,077.

To all whomz't may concern 7 Be it known that we, HENRY CLAYTON WOOD andVVRIGHT HINCHCLIFF BROOK, subj ects of the King of Great Britain and Ireland, residing, respectively, at Tadcaster and at Bilbrough, both in thecounty of York, England, have invented a new and useful ImprovedCombination Dishstone, Gully-Trap, and Drain Connection for Use inSanitary WVork, of which the following is a specification.

This invention relates to an improved combination dishstone, gully-trap,and drain connection pipe, for use in sanitary work.

The object of our invention is to combine, with an accessiblewater-sealed gully-trap designed to open and expose in sectionalelevation the whole of the interior surface of the trap, and with anyordinary form of dishstone to which such accessible trap may be applied,a special form of drain connection having means for preventing orchecking the escape of any sewer gas or stench from the drains duringthe period the trap is opened for cleansing purposes.

In the accompanying drawings Figure 1 is a front elevation of ourimproved combination dishstone, gully-trap, and drain connection, theaccessible gully-trap being shown in its normal or closed position. Fig.2 is a side elevation of Fig. 1. Fig. 3 is a plan of the dishstone. Fig.4 is a sectional front elevation of the combination dishstone,gully-trap, and drain connection, in section on the line D D of Fig. 5,and showing the accessible gully-trap in its open position. Fig. 5 is asectional side elevation of Fig. l,

7 in section on the line A A, but with the accessible gully-trap closed.Fig. 6 is a plan on the line C C of Fig. 4, that is to say, with thedishstone removed. Fig. 7 is a sectional plan of the drain connection,in section on the line B B of Fig. l.

According to our said invention, we provide a dishstone E of anyordinary form, having ordinary outlet and plug or grating F, andsupported or suspended in a suitably elevated position so as toprovidethe necessary opening or space for interposition of theaccessible water-sealed gully-trap G between the dishstone outlet andthe level of the drain H to be connected to. T his accessiblewater-sealed gully-trap G is of the type described in the specificationof our pending application Serial No. 58076, and provides for the wholeof the interior surface of the trap being fully exposed to view forinspection purposes and to facilitate cleansing and the removal of anyfilth, deposit, or obstruction in the trap or in the pipes immediatelyconnected therewith. The inlet pipe of the trap is formed with a socketI connecting loosely with a corresponding lip J on the dishstone outlet,or any other ordinary form of joint or connection between the dishstoneand the trap may be employed.

In combination with the accessible watersealed gully-trap and dishstoneas hereinbefore described, we provide a separate drain connection pipe Kbetween the gullytrap outlet pipe and the drain H, said pipe K beingconnected detachably to the outlet pipe of the trap by bolted flanges Lor other convenient means, and being jointed in any ordinary manner atits opposite end to the drain pipe II. This drain connection pipe K isfitted with an internal adjustable valve device, consisting preferablyof a hinged flap M engaging over a water-sealed seating N and having anexternal counterbalanced controlling handle 0, this valve device beingdesigned to prevent or minimize the escape of foul gas into theatmosphere through the outlet pipe of the gully-trap during theoperation of cleansing the trap when the door of the trap is open andthe water seal of the trap isbroken.

If desired a door or doors or other form of easing may be provided toinclose the space beneath the dishstone E; or the combination dishstone,gully-trap, and drain connection pipe may be inclosed within a manholeor inspection chamber so that the dishstone may be arranged at groundlevel.

We claim:

1. The combination, with an accessible water-sealed gully-trap of thetype designed to open and expose in sectional elevation the whole of theinterior surface of the trap, and with any ordinary form of dishstone towhich said trap may be applied, of a drain connection pipe jointed atone end to the drain pipe and detachably connected at the other end tothe outlet pipe of the trap, and having an externally-controlledinternal valve device for preventing or minimizing the cs- IOU v Wholeof the interior surface of the trap, and

other end to. the outlet pipe o'fthe...trap, and having anexternally-controlled internal Valve device comprising hinged internalflap M, internal seating N, and external 'counterbalanced controllinghandle 0, substantially as herein set forth. a

cape of foul gas from the drain during such period as the trap may beopened for cleanse. ing purposes.

2. The combination, with an accessible Water-sealed gully-trap of thetype designed to open and expose in sectional elevation the with anyordinary form of dishstone to which said trap may be applied, of a drainconnection pipe jointed at oneend to the drain pipe and detachablyconnected at the Gopiesof this patent may be obtained for five centseach, by addressing the Commissioner of Patents,
